2023-12-11libgfortran: Replace mutex with rwlockLipeng Zhu3-0/+73
This patch try to introduce the rwlock and split the read/write to unit_root tree and unit_cache with rwlock instead of the mutex to increase CPU efficiency. In the get_gfc_unit function, the percentage to step into the insert_unit function is around 30%, in most instances, we can get the unit in the phase of reading the unit_cache or unit_root tree. So split the read/write phase by rwlock would be an approach to make it more parallel. BTW, the IPC metrics can gain around 9x in our test server with 220 cores. The benchmark we used is https://github.com/rwesson/NEAT libgcc/ChangeLog: * gthr-posix.h (__GTHREAD_RWLOCK_INIT): New macro. (__gthrw): New function. (__gthread_rwlock_rdlock): New function.

2023-12-11aarch64: enable mixed-types for aarch64 simdclonesAndre Vieira2-3/+13
This patch enables the use of mixed-types for simd clones for AArch64, adds aarch64 as a target_vect_simd_clones and corrects the way the simdlen is chosen for non-specified simdlen clauses according to the 'Vector Function Application Binary Interface Specification for AArch64'.

2023-12-08OpenMP/Fortran: Implement omp allocators/allocate for ptr/allocatablesTobias Burnus12-7/+417
This commit adds -fopenmp-allocators which enables support for 'omp allocators' and 'omp allocate' that are associated with a Fortran allocate-stmt. If such a construct is encountered, an error is shown, unless the -fopenmp-allocators flag is present. With -fopenmp -fopenmp-allocators, those constructs get turned into GOMP_alloc allocations, while -fopenmp-allocators (also without -fopenmp) ensures deallocation and reallocation (via intrinsic assignments) are properly directed to GOMP_free/omp_realloc - while normal Fortran allocations are processed by free/realloc. In order to distinguish a 'malloc'ed from a 'GOMP_alloc'ed memory, the version field of the Fortran array discriptor is (mis)used: 0 indicates the normal Fortran allocation while 1 denotes GOMP_alloc. For scalars, there is record keeping in libgomp: GOMP_add_alloc(ptr) will add the pointer address to a splay_tree while GOMP_is_alloc(ptr) will return true it was previously added but also removes it from the list. Besides Fortran FE work, BUILT_IN_GOMP_REALLOC is no part of omp-builtins.def and libgomp gains the mentioned two new function. gcc/ChangeLog: * builtin-types.def (BT_FN_PTR_PTR_SIZE_PTRMODE_PTRMODE): New. * omp-builtins.def (BUILT_IN_GOMP_REALLOC): New. * builtins.cc (builtin_fnspec): Handle it. * gimple-ssa-warn-access.cc (fndecl_alloc_p, matching_alloc_calls_p): Likewise. * gimple.cc (nonfreeing_call_p): Likewise. * predict.cc (expr_expected_value_1): Likewise. * tree-ssa-ccp.cc (evaluate_stmt): Likewise. * tree.cc (fndecl_dealloc_argno): Likewise. gcc/fortran/ChangeLog: * dump-parse-tree.cc (show_omp_node): Handle EXEC_OMP_ALLOCATE and EXEC_OMP_ALLOCATORS. * f95-lang.cc (ATTR_ALLOC_WARN_UNUSED_RESULT_SIZE_2_NOTHROW_LIST): Add 'ECF_LEAF | ECF_MALLOC' to existing 'ECF_NOTHROW'.

2023-12-06amdgcn, libgomp: low-latency allocatorAndrew Stubbs7-10/+188
This implements the OpenMP low-latency memory allocator for AMD GCN using the small per-team LDS memory (Local Data Store). Since addresses can now refer to LDS space, the "Global" address space is no-longer compatible. This patch therefore switches the backend to use entirely "Flat" addressing (which supports both memories). A future patch will re-enable "global" instructions for cases where it is known to be safe to do so. gcc/ChangeLog: * config/gcn/gcn-builtins.def (DISPATCH_PTR): New built-in. * config/gcn/gcn.cc (gcn_init_machine_status): Disable global addressing.

2023-12-06openmp, nvptx: low-lat memory access traitsAndrew Stubbs10-6/+166
The NVPTX low latency memory is not accessible outside the team that allocates it, and therefore should be unavailable for allocators with the access trait "all". This change means that the omp_low_lat_mem_alloc predefined allocator no longer works (but omp_cgroup_mem_alloc still does). libgomp/ChangeLog: * allocator.c (MEMSPACE_VALIDATE): New macro.

2023-12-06libgomp, nvptx: low-latency memory allocatorAndrew Stubbs12-105/+1239
This patch adds support for allocating low-latency ".shared" memory on NVPTX GPU device, via the omp_low_lat_mem_space and omp_alloc. The memory can be allocated, reallocated, and freed using a basic but fast algorithm, is thread safe and the size of the low-latency heap can be configured using the GOMP_NVPTX_LOWLAT_POOL environment variable. The use of the PTX dynamic_smem_size feature means that low-latency allocator will not work with the PTX 3.1 multilib. For now, the omp_low_lat_mem_alloc allocator also works, but that will change when I implement the access traits. libgomp/ChangeLog: * allocator.c (MEMSPACE_ALLOC): New macro.

The patch 'openmp: Add support for the 'indirect' clause in C/C++' introduced a new file target-indirect.c into the Makefile sources, but that file was only present in config/linux/ and config/accel/, so targets that are not Linux-based or GPU accelerators will not pick it up and fail to build.

This patch implements the 'self' clause for compute constructs: parallel, kernels, and serial. This clause conditionally uses the local device (the host mult-core CPU) as the executing device of the compute region. The actual implementation of the "local device" device type inside libgomp (presumably using pthreads) is still not yet completed, so the libgomp side is still implemented the exact same as host-fallback mode.

2023-10-22Config,Darwin: Allow for configuring Darwin to use embedded runpath.Iain Sandoe4-9/+130
Recent Darwin versions place contraints on the use of run paths specified in environment variables. This breaks some assumptions in the GCC build. This change allows the user to configure a Darwin build to use '@rpath/libraryname.dylib' in library names and then to add an embedded runpath to executables (and libraries with dependents). The embedded runpath is added by default unless the user adds '-nodefaultrpaths' to the link line. For an installed compiler, it means that any executable built with that compiler will reference the runtimes installed with the compiler (equivalent to hard-coding the library path into the name of the library). During build-time configurations any "-B" entries will be added to the runpath thus the newly-built libraries will be found by exes. Since the install name is set in libtool, that decision needs to be available here (but might also cause dependent ones in Makefiles, so we need to export a conditional). This facility is not available for Darwin 8 or earlier, however the existing environment variable runpath does work there. We default this on for systems where the external DYLD_LIBRARY_PATH does not work and off for Darwin 8 or earlier. For systems that can use either method, if the value is unset, we use the default (which is currently DYLD_LIBRARY_PATH). ChangeLog: * configure: Regenerate. * configure.ac: Do not add default runpaths to GCC exes when we are building -static-libstdc++/-static-libgcc (the default). * libtool.m4: Add 'enable-darwin-at-runpath'.

2023-10-20amdgcn: add -march=gfx1030 EXPERIMENTALAndrew Stubbs2-3/+9
Accept the architecture configure option and resolve build failures. This is enough to build binaries, but I've not got a device to test it on, so there are probably runtime issues to fix. The cache control instructions might be unsafe (or too conservative), and the kernel metadata might be off. Vector reductions will need to be reworked for RDNA2. In principle, it would be better to use wavefrontsize32 for this architecture, but that would mean switching everything to allow SImode masks, so wavefrontsize64 it is. The multilib is not included in the default configuration so either configure --with-arch=gfx1030 or include it in --with-multilib-list=gfx1030,.... The majority of this patch has no effect on other devices, but changing from using scalar writes for the exit value to vector writes means we don't need the scalar cache write-back instruction anywhere (which doesn't exist in RDNA2). gcc/ChangeLog: * config.gcc: Allow --with-arch=gfx1030. * config/gcn/gcn-hsa.h (NO_XNACK): gfx1030 does not support xnack.

2023-10-20omp_lib.f90.in: Deprecate omp_lock_hint_* for OpenMP 5.0Tobias Burnus1-0/+4
The omp_lock_hint_* parameters were deprecated in favor of omp_sync_hint_*. While omp.h contained deprecation markers for those, the omp_lib module only contained them for omp_{g,s}_nested. Note: The -Wdeprecated-declarations warning will only become active once openmp_version / _OPENMP is bumped from 201511 (4.5) to 201811 (5.0). libgomp/ChangeLog: * omp_lib.f90.in: Tag omp_lock_hint_* as being deprecated when _OPENMP >= 201811.

2023-10-15libgomp.texi: Update "Enabling OpenMP" + OpenACC / invoke.texi: ↵Tobias Burnus1-13/+18
-fopenacc/-fopenmp update The OpenACC specification does not mention the '!$ ' sentinel for conditional compilation and the feature was removed in r11-5572-g1d6f6ac693a860 for PR fortran/98011; update libgomp.texi for this and update a leftover comment. - Additionally, some other updates are done as well. libgomp/ * libgomp.texi (Enabling OpenMP): Update for C/C++ attributes; improve wording especially for Fortran; mention -fopenmp-simd. (Enabling OpenACC): Minor cleanup; remove conditional compilation sentinel. gcc/ * doc/invoke.texi (-fopenacc, -fopenmp, -fopenmp-simd): Use @samp not @code; document more completely the supported Fortran sentinels. gcc/fortran * scanner.cc (skip_free_comments, skip_fixed_comments): Remove leftover 'OpenACC' from comments about OpenMP's conditional compilation sentinel.
2023-10-15libgomp.texi: Improve "OpenACC Environment Variables"Tobias Burnus1-11/+20
None of the ACC_* env vars was documented; in particular, the valid valids for ACC_DEVICE_TYPE found to be lacking as those are not document in the OpenACC spec. GCC_ACC_NOTIFY was removed as I failed to find any traces of it but the addition to the documentation in commit r6-6185-gcdf6119dad04dd ("libgomp.texi: Updates for OpenACC."). It seems to be planned as GCC version of the ACC_NOTIFY env var used by another compiler for offloading debugging. libgomp/ * libgomp.texi (ACC_DEVICE_TYPE, ACC_DEVICE_NUM, ACC_PROFLIB): Actually document what the function does. (GCC_ACC_NOTIFY): Remove unused env var.

2023-10-14libgomp.texi: Note to 'Memory allocation' sect and missing mem-memory routinesTobias Burnus1-15/+367
This commit completes the documentation of the OpenMP memory-management routines, except for the unimplemented TR11 additions. It also makes clear in the 'Memory allocation' section of the 'OpenMP-Implementation Specifics' chapter under which condition OpenMP managed memory/allocators are used. libgomp/ChangeLog: * libgomp.texi: Fix some typos. (Memory Management Routines): Document remaining 5.x routines. (Memory allocation): Make clear when the section applies.

gcc/fortran/ChangeLog: * gfortran.h (ext_attr_t): Add omp_allocate flag. * match.cc (gfc_free_omp_namelist): Void deleting same u2.allocator multiple times now that a sequence can use the same one. * openmp.cc (gfc_match_omp_clauses, gfc_match_omp_allocate): Use same allocator expr multiple times. (is_predefined_allocator): Make static. (gfc_resolve_omp_allocate): Update/extend restriction checks; remove sorry message. (resolve_omp_clauses): Reject corarrays in allocate/allocators directive. * parse.cc (check_omp_allocate_stmt): Permit procedure pointers here (rejected later) for less misleading diagnostic. * trans-array.cc (gfc_trans_auto_array_allocation): Propagate size for GOMP_alloc and location to which it should be added to. * trans-decl.cc (gfc_trans_deferred_vars): Handle 'omp allocate' for stack variables; sorry for static variables/common blocks. * trans-openmp.cc (gfc_trans_omp_clauses): Evaluate 'allocate' clause's allocator only once; fix adding expressions to the block. (gfc_trans_omp_single): Pass a block to gfc_trans_omp_clauses. gcc/ChangeLog: * gimplify.cc (gimplify_bind_expr): Handle Fortran's 'omp allocate' for stack variables. libgomp/ChangeLog: * libgomp.texi (OpenMP Impl.
